Methink you're a little confused. A function is a piece of code that
performs a specific job that can be called. You may send it
data, you may not. It may return data, it may not. If your link goes to
logout.php, that script may use functions to do it's job.
You can't call a function in a link as php is server-side. What you are
thinking of is an event handler, ie client side (javascript).
Example of how you could achieve what you want:
logout.php
========
include 'logfunctions.php'
logout($_GET['id']);
header("Location: index.php");
exit();
logfunctions.php
============
function logout($id) {
unset($id);
}
etc etc etc - crude example but pushed for time and you get the idea!
